Abstract: PURPOSE:To stabilize delay time by providing a phase shifter measuring the delay time and automatically-selecting the number of stages of a delay unit. CONSTITUTION:A switch 3 is normally on a (b) side, and a signal from a signal input terminal 2 is supplied to a delay line 5. At the time of measuring delay time, it is connected to an (a) side, and a signal S0 of time width T for measuring delay time from a pulse generator 1 is supplied to the DATA input of a first step of delay unit 41 and all latch circuits 7. As the number of stages of units 41 to 4n become deeper, signals S1 to Sn with larger delay time can be obtained. When the signal S0 is latched by the rising of the signal obtained by a unit 4 in circuits 71 to 7n, it becomes an H level when latched by pulses S1 to S4, and an L level when latched by pulses S5 to Sn. To obtain the delay of alphaT time, the data of a coefficient alpha is inputted by a delay time setting input terminal 10, and a changeover device 11 is controlled by a result alphaA multiplied by the prescribed time delay stage number A. Thus, the delay time can be stabilized.

Title: Fuel injection controller for internal combustion engine
Inventor: SHIRAKAWA AKIRA
IPC: F02D1/18
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent the control accuracy of injection timing control from being deteriorated by controlling a static injection timing controlling means based on a target value calculated by a target value converting and calculating means and a detected value calculated by a detected valu converting and calculating means. SOLUTION: Injection delay period is detected from dynamic injection timing detected from a needle valve lift sensor 114A fitted on a fuel injection valve 114 and static injection timing detected from a timer piston position sensor 112. Based on this, the target injection timing given as the dynamic injection timing is converted into static injection timing (timer piston position), and a timing control valve 113 is controlled so that the timer piston position necessary to obtain the target dynamic injection timing may be attained. It is thus possible to prevent the control accuracy of injection timing from being deteriorated because of control response delay at the time of transient operation.

Abstract: PROBLEM TO BE SOLVED: To provide a rotary head type recording/reproducing device which can cope with the signals of a plurality of information rates and a plurality of track pitches while heads which face each other with a phase difference of an approximately 180 degrees are not used simultaneously and the complexity of a processing circuit is avoided. SOLUTION: A head 2b and a head 2c are placed in proximity with a counter position of a head 2a with 180 degrees difference as a center between the head 2b and the head 2c. The phases of a head 2d and a head 2e are different from the phase of the head 2a by 90 degrees respectively. Low rate signals are recorded/reproduced by using the heads 2b and 2c, standard rate signals are recorded/reproduced by using the heads 2a and 2c and high rate signals are recorded/reproduced by using the heads 2a, 2d, 2b and 2e. With this constitution, as the head 2b and the head 2c are placed in proximity with the position 180 degrees apart from the head 2a as the center between them, an angle between the head 2a and the head 2b and an angle between the head 2a and the head 2c are maximum.  Therefore, the heads in the above-mentioned combinations do not operate simultaneously and hence the complexity of a processing circuit can be avoided.

Title: Optical fiber
Inventor: HAMA YOSHINORI
IPC: G02F1/01
Filed: 1985-12-04
Abstract: PURPOSE:To control a plane of polarization of light propagating through optical fiber and to avoid damage of the optical fiber by utilizing piezoelectric effect of a layer of a piezoelectric body. CONSTITUTION:When a control voltage is applied across an internal surface electrode 3 and an external surface electrode 5, a displacement in proportion to the voltage is generated by the piezoelectric effect in a part interposed between the internal surface electrode 3 and the external surface electrode 5 of the layer 4 of the piezoelectric body. A stress is generated in the piezoelectric body layer 4 because the deformation is inhibited by a covering layer 6 having high Young's modulus in its external periphery, and a clad layer 2 is pressed from its side surface by the stress. On one hand, since no piezoelectric effect is generated in the piezoelectric body layer 4 which is not interposed between the internal surface electrode 3 and the external surface electrode 5, no stress pressing the clad layer 2 from its side surface is generated. Thus, asymmetric internal stress is generated in the core 1, and a difference of transmission velocity is generated between the Ex mode and Ey mode. Thus, the plane of polarization of light propagating through an optical fiber 10 can be controlled by controlling applied voltage to the electrode 3 and 5.
